1.2.6

breaking changes

1. remove interval arg from perf-collect
2. remove percore, persocket and cloud flags from perf-postprocess (now detects arguments from perf-collect output)
3. changed output file naming to sys.out (for system-wide), socket.out (for socket-level), and core.out (for core-level)

general bug fixes and enhancements:

1. added LLC MPI metrics for ice lake
2. added verbose logging to perf-postprocess
3. removed temporary calculation csv output
4. aligned CLX and SKX metric names with other Xeon generations like changing TMAM to TMA

1.2.5

Possibly breaking changes:

1. remove -csp and -ct flags and detects if in vm and removes noncore events
2. removed flags (metadata only, dry-run, eventfile)
3. requires sudo/root to run
4. General bug fixes and cleanup:

filter OCR and power events when in core only mode

1. add example deamonset.yml
2. added logging
3. update readme with centos minimum kernel requirements

1.2.4

Possibly breaking changes:

1. change cid mode output file format to match pid and system-wide runmodes with min max and p99

General bug fixes and cleanup:

1. fix cid invalid errors to support cgroup v1 and v2
2. fix percore processing error on icx
3. port pmu checker to python
4. improve accuracy of dram bandwidth
5. remove unneeded files

1.2.3

1- fixes metric CPU Util% with pid argument
2- adds more info to README
3- detects missing dependencies

1.2.2

1. fixes libinfo warnings thrown on ubuntu 16.04
2. change make dist to make
3. close nmi file
4. handle msr read errors without panic
